The 10, which prevent loss of heat by radiation. said sprocket-chains are connected together Between the upper casing and the inner casby suitable cross-rods 30. The said chains, ing, ,which form the top of the heating and cross-rods, and sprocket wheels constitute an drying chamber, is formed a flue 11. A box endless traveling carrier. One lead of the 5 12 is formed on thetop of the said heating and carrier passes longitudinally through theheat= drying chamber, which box is adapted to be ing and drying chamber,.above the crownfilled with sand or other suitable non-consheet 14, and through the doorways at the ducting material. One end of theheating ends of the heating and drying. chamber. and drying chamber is disposed directly over The lower lead of the endless carrier passes mo the fire-box, and the latter is provided with under the ash-pit and is engaged by sheaves a flue 13, which extends longitudinally under 31, which keep the chains tight.

Within the scope of my invention any suitable means may be employed for operating the endless carrier. For this purpose I here show the shaft 27 as provided with a gearwheel 32, which is engaged by a pinion 33 on a power-shaft 34. The latter has a conepulley 35, by means of which it may be driven at any desired rate of speed by a belt from a counter-shaft, as will be readily understood.

The tubs or other articles to be dried and heated are placed on the endless carrier at one end of the heating and drying chamber, and the latter being heated,the doors thereof being opened,and the endless carrier being set in motion the said tubs or other articles are conveyed into and through the drying-chamber and dried during their passage through the same. It will be understood that the endless carrier serves to run the tubs or other articles into, through, and out of the heating and drying chamber and that tubs or other articles are placed on said carrier at one end of the heater and removed therefrom after having been carried through the heater, and hence the operation of my heating and drying apparatus is continuous. The doors 18 are only closed while the heating and drying chamber is being initially heated and are kept open while the apparatus is in use.

Having thus described my invention, I

rier having one lead disposed in and adapted to travel longitudinally through said heating and drying chamber, substantially as described.

2. In a heater and drier of the class described, the combination with a fire-box having a flue leading therefrom, of a heating and drying chamber having one end disposed over said fire-box, said heating and drying chamber comprising an inner and outer casing, the spaces between the sides of said casings forming non-radiating chambers, the said sides of said chamber having uptake -flues formed therein at one end thereof and communicatin g with the fine of the fire-box, and the space between the said inner and outer casings on the top of the said heating and drying chamber forming an escape-flue which leads from the said uptakefines; a crown-sheet over said fire-box and the flue leading therefrom and under said heating and drying chamber; and an endless carrier having one lead adapted to travel through and disposed in said heating and drying chamber, over said crownsheet, substantially as described.

3. Aheater and drier of the class described comprisingaheatingand drying chamberhaving an escape-flue extending longitudinally above the same, uptake-fines in the sides of said chamber and communicating with said escape-flue, a fire-box under said chamber and having a due leading to said uptake-fines, and a carrier extending through said chamber, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two witnesses.
